To provide a kerosene stove having a combustion chamber structure allowing a continuance of combustion in an always stable flame state, causing no incomplete combustion state.

In this kerosene stove, kerosene supplied from a kerosene supply chamber is burned inside a combustion chamber formed by an outer flame cylinder and an inner flame cylinder positioned inside an outer cylinder, and the kerosene supply chamber and a kerosene storage chamber around the kerosene supply chamber are connected by two communication pipes. In the combustion chamber structure of the kerosene stove, a blasting process is applied to at least combustion-side surfaces of the outer flame cylinder and the inner flame cylinder forming the combustion chamber to form the rough surfaces.
